This ingenious life hack turns your hot water bottle into a summer savior!

The trick is so simple that you'll wonder why you didn't think of it sooner: Instead of hot water, fill your hot water bottle with ice-cold tap water. Then put it in the fridge for a few hours or, if you're in a hurry, in the freezer for a short time. The flexible material of the hot water bottle is the real game-changer. It perfectly adapts to your body contours and delivers the cold exactly where you feel it the most.

To get the maximum freshness kick, place the icy hot water bottle on your pulse points. Think wrists, neck, or ankles. Here, your blood vessels are directly under the skin, and the cold is quickly conducted through your body. You'll be amazed at how quickly the unbearable heat subsides!

Step-by-step to the perfect cooling bottle

Ready? It's that easy:

Depending on the room temperature, the cooling effect lasts between 30 minutes and two hours. Enough time to finally drift off to dreamland on tropical nights!

But safely! How to protect yourself from cold damage

Safety first! The ice-cold bottle should not be placed directly on the skin. Otherwise, it can lead to cold damage, such as redness, numbness, or even nasty blisters. A towel or a thin fabric as a barrier between the bottle and the skin is an absolute must. This way, you can enjoy the cooling without any risk.

No hot water bottle at hand? No problem! A regular PET bottle works just as well. Simply fill it with cold water, put it in the fridge, and then, of course, wrapped in a cloth, apply it. PET bottles are super flexible and lightweight – perfect for on the go when the heatwave follows you everywhere.

Just a small warning: Keep your hands off glass bottles! They can crack or even break in extreme cold, and nobody wants that. It's better to invest in a real hot water bottle – it's not only your cooling hero in summer but also your cuddly buddy in winter.
